Hi, A makes call to B. B has connection problem with the server (say, the lan cable is unplugged). 1: A ---> server 2: A <--- server 3: server ----> B In 2, server will send the ring to A and it will hear ringing tone. In 3, server will try to connect B until timeout. My question is: A will still wait for B but B is physical unreachable. Can I set the number of retry time in server to try to reach the destination instead of the timeout?
